Perciformes: Percoidei: Bramidae 1469

BRAMIDAE by B.A. Thompson, Louisiana State University, USA (modified from Haedrich 1977) iagnostic characters: Medium- to large-sized fishes attaining nearly 1 m total length; body deep and Dsometimes very compressed;head fairly deep, eyes large and located on side of head;mouth large with heavy jaws; maxilla broad and covered with scales; a single long-based dorsal fin, longer or equal in length to anal fin that is very similar to dorsal fin; both dorsal and anal fin with several spines in anterior part of fin, but not easily distinguished from rays;large caudal fin is often deeply forked;pectoral fins long and wing-like; both pectoral and pelvic fins with scaled axillary processes;pelvic fins often short, always with 1 spine and 5 rays; lateral line can be poorly formed or absent in some adults; scales large, often keeled or modified with spinous projections; scales cover body and head except for certain species with naked patches at snout and near eyes. Colour: most species are black, sometimes with flecks of silver.

single long-based dorsal fin scales large, often keeled, or with spinous projections

anal fin similar in size and shape to dorsal fin maxilla broad and covered with scales

Habitat, biology, and fisheries: Epi- and mesopelagic found in temperate and warm-temperate oceans, ex- cept for Eumegistus which is more benthic. Predators on small fishes and macroinvertebrates such as squid. They appear to be nearly year-round batch spawners as a family.Most species undergo a remarkable transfor- mation in fin and body shape as they grow. Several genera (e.g. , Taractichthys) are taken by longline and vertical line, but no directed fishery in Area 31 even though they are excellent foodfish. Remarks: Thompson and Russell (1996) listed 22 species in 7 genera. no lateral line Similar families occurring in the area Diretmidae: size small (usually less than 25 cm), abdomen keeled, with a row of scutes in front of anal fin; lateral line ab- sent; pelvic fins with 1 spine and 6 soft rays (5 soft rays in Bramidae). row of scutes in front of anal fin

Lampridae: somewhat similar in shape, but brightly coloured, especially fins and jaws (bright scarlet); also, mouth smaller and pelvic fins about as large as pectoral fins, the latter with a horizontal base. Stromateidae:also somewhat similar in shape, but has a small mouth, lacks pelvic fins and has very thin, small scales which are easily shed.

Habitat, biology, and fisheries: Adult rovers occur near the bottom at depths of 57 to 500 m in tropical and warm-temperate waters of all oceans;postlarvae and small lateral view of head juveniles (less than 7 cm standard length) are apparently epipelagic, at least during the night, when they have been collected in depths of 0 to100 m over deep water. Rovers inhabit continental shelves and upper slope regions and are also common at some oceanic islands and sea mounts. Little is known of their biology; rovers feed on zooplankton, especially colonial salps. Taken mainly as bycatch in trawls; the flesh is excellent. Remarks: The family comprises 3 genera and 15 species. 1476 Bony Fishes

Dorsal fin with 11 spines and 11 or 12 rays; fin margin notched to base in front of soft portion; anal fin with 3 spines and 9 or 10 rays. Anal and soft dorsal fins with scaly sheath at base that is best developed posteriorly, where it covers most of the posterior 2 or 3 rays. Caudal fin forked, heavily scaled at base; principal caudal rays 9+8, branched rays 8+7.Specimens larger than 30 cm standard length with a well-developed, fleshy midlateral keel along rear part of caudal peduncle and continuing onto base of caudal fin.Pectoral fin with 18 to 20 rays; pelvic fins with a well-developed scaly axillary process of fused scales, and a midventral scaly process between fins.

Colour: head and body reddish, darker dorsally, silvery laterally and ventrally; dorsal, anal, and pelvic fins pinkish white; caudal and pectoral fins reddish. Size: Maximum total length 55 cm. Habitat, biology, and fisheries: Found near the bottom in depths of 100 to 300 m. Nothing has been published on the biology of this species. Probably feeds on macrozooplankton and small fishes. Taken mainly as bycatch in trawl fisheries. Not abundant, but the flesh is excellent. Distribution: South Carolina, northern Gulf of Mexico, Bahamas, Colombia, Venezuela, St Lu- cia in Windward Islands; also known in the east- ern Atlantic from Mauritania, Senegal, Gambia, the Gulf of Guinea, Congo, and Angola, and one recent record from the Bay of Biscay on the Atlan- tic coast of France. 1478 Bony Fishes

Emmelichthys ruber (Trunov, 1976) En - Island rover. Maximum size to 23 cm.Adults and large juveniles (more than 10 cm standard length) occur near the bottom in depths of 180 to 200 m; postlarvae and juveniles less than 7 cm standard length are apparently epipelagic. Feeds on zooplankton. Although the island rover is common at some localities, the small size of this species and the steeply-sloping rugged bottom habitat make it difficult to catch commercial quantities. Bermuda, east- ern Gulf of Mexico, Jamaica, and St. Helena, but probably more widespread.
